Produktionsvåtmarker mot övergödning

In ambition to produce more and better harvests, artificial fertilizers are used to produce a better growth of crops in the agriculture landscape. This contributes to leakage of nutrients. Our forests also exhibit a leakage of nutrients. Air pollution contributes to more nutrients. High precipitation with high water flows as a consequence seems currently to occur more frequently in the county of Halland.

Fiolteknik i folkmusikundervisningen

Title: Violin technique in folk music education. The purpose of this research has been to examine how violin teachers who are folk musicians teach violin playing techniques. Through litterature studies and qualitative interviews I have studied the relationship between teaching methods regarding violin playing techniques of the two genres folk music and classical music and how the teachers in the study relate to this. Mywork shows that the teachers use a variety of methods and material from both genres which they have come in contact with through different parts of their education.Jag har undersökt hur fyra fiollärare inom genren folkmusik arbetar med fiolteknik med sina elever. Genom litteraturstudier och kvalitativa intervjuer har jag undersökt relationen mellan undervisningstraditioner för teknikövning inom genrerna folkmusik och klassisk musik och hur lärarna förhåller sig till detta.

Legionella i tappvattensystem. Förekomst och förebyggnade-en redogörelse.

A comprehensive written publication for Legionella-safe plumbing installations is not available and therefore requested. The purpose of this report is to present preventative measures against Legionella bacteria growth in tap water and in other systems where Legionella bacteria are a potential problem. Technical solutions are presented including how different systems function and what their advantages and disadvantages are.

Höjning av vattennivån i Mälaren : Ett hot mot Stockholms centrala delar vid en framtida klimatförändring?

In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.

Folk i allmänhet har taskig smak En studie av vanliga läsares kvalitetsvärdering av skönlitteratur

The aim of this study is to investigate ordinary readers' evaluation of quality in literature. The main issue is which criteria ordinary grown-up readers use when they are defining their likes and dislikes in literature. The analysis is based upon qualitative interviews with six readers, two men and four women, between 21 and 59 years of age. The study is hermeneutic. Since theoretical works concerning evaluation of literature among ordinary readers are sparse, the philosopher of arts and religion Hugo A.

Från a till b via d h och ö : Det ickelinjära berättandet i modern tid

How do we perceive literature? In our times computer games and Internet have made us grow more comfortable to the usage of non linear storylines. But how does this apply to printed literature?In this essay, called ?From a to b through d h and o. Non linear storytelling in our time? I have focused on nonlinear literature from different time periods and I have studied novels such as James Joyce?s Ulysses as well as works by William S.

Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp

At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.

En uppföljning av floran i Enköpings vattenpark : kan anlagda våtmarker med vattenrening som huvudsyfte bidra till naturvård och biologisk mångfald?

Wetlands are important ecosystems and form habitat for both common and threatened species. In Sweden, as well in many other places on earth, there is a lack of wetlands. There is an expressed will to adjust this lack through restoration of wetlands with reduced function and through construction of new wetlands. Follow-ups and evaluations are important steps to optimize these actions. The wetland Vattenparken was constructed 1999 ? 2000 for treatment of surface water.

H.P. Lovecraft : Narratologisk analys av atmosfär och fasor

Even though the American author H.P. Lovecraft (1890-1937) has been praised as one of the most influential writers of horror literature in the 20th century, his style of writing has occasionally been criticized. Lovecraft was using a writing style based on strict scientific language, where the human condition and existence are irrelevant in the narrative. This includes less focus on character development and more on the importance of atmosphere and environments. I am presenting narratological analyzes of what is often considered to be three of Lovecraft?s ?greatest works?: ?The Call of Cthulhu?, At the Mountains of Madness, and ?The Shadow over Innsmouth.? These analyzes are used to highlight Lovecraft?s science-oriented language and narratological techniques, with the focus of studying what methods Lovecraft was using to give his works and his readers a sense of dread, hopelessness, and an alien atmosphere.

Energiinventering av Soldathemmet

This examination paper is an energy-inventory of Soldathemmet at the regement in Halmstad, in colaboration with Fortifikationsverket in Halmstad. The building is first an foremost for the soldiers, where they can go for a cup of coffee or watch TV. There is also a museum and a drivers school in the building. Calculations have been done with two computerprograms; VIP+ and ISOVER Energy. The results were well matched with the statistics that were provided by Fortifikationsverket.

Phycoremediation of pesticides using microalgae

Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity in biosorbing heavy metals.

Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd

The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth. Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.

Etiska aspekter av preimplantatorisk genetisk diagnostik och genterapi

The research in the field of biotechnology is rapidly developing all over the world. Modern biotechnology offers unique opportunities, simultaneously as it gives rise to a number of ethical issues. Preimplantation genetic diagnosis (PGD), PGD/HLA (Human Leucocyte Antigen) and germline gene therapy (GLGT) are controversial techniques. PGD gives a possibility to identify a genetic disease prior to the embryo?s implantation in the uterus.

Att möta det okända : Utmaningar vid implementering av ett processorienterat arbetssätt inom offentlig verksamhet

This paper aims to shine a light on the challenges connected to the implementation of a process focused way of thinking in a public service organization. To this we have conducted a series of qualitative interviews, primarily from participants of a university driven project. The project aims to teach decision making employees of public service organizations how to use process modeling techniques to increase their efficiency. We have also interviewed the teachers who have taught the courses included in the project. As a final point of view we have also interviewed a researcher and IT consultants to compare novice users with experienced users of process modeling techniques.
